A Hedgehog

According to BuzzFeed, California and New York are the only states that you can't legally have a hedgehog as a pet, but everywhere else is fair game. They are nocturnal for the most part so they'll be up at night time. They do make very adorable noises too. (Look it up on YouTube)

A Fox

According to The Spruce, the only type of domesticated fox is the Siberian Fox. They are sometimes red and sometimes gray, and can weigh up to around 22 pounds. Domesticated foxes also can eat Grain Free dog food brands, but are considered omnivores. The issue isn't so much the care of the fox, but the initial price of the fox, because getting a domesticated fox pup can cost up to $7,000.
